Bio-identification described in the present embodiment refers to any one in fingerprint recognition, the identification of palm shape, shape of face identification, iris recognition, speech recognition.The present embodiment be take fingerprint recognition as example description.
The doorway main frame that the present embodiment provides comprises fingerprint identification module, communication module, CCD/CMOS video heads, Electret condenser microphone and loudspeaker, button and LED/LCD display, door lock control circuit and the power circuit that is connected to microprocessor, and communication module is by split conductor or netting twine or wireless connections subscriber's extension station.Subscriber's extension station comprises communication module, CRT or liquid crystal display, Electret condenser microphone and loudspeaker, the button that is connected to microprocessor, and communication module is by split conductor or netting twine or wireless connections doorway main frame.The present embodiment is to implement on the hardware foundation based on existing building conversational system, but inventive point do not lie in hardware, but the method for implementing on this hardware and system thereof.
As shown in Figure 1, the biological information recognition method of the present embodiment mainly comprises step S10-S40:
Step S10: detect the mandate that whether obtains selective call subscriber's extension station when doorway main frame and selective call subscriber's extension station are communicated with, if so, doorway main frame reads user's fingerprint and is stored to selective call subscriber's extension station as fingerprint counterfoil.
As shown in Figure 2, in step 101, specifically comprise step S101-S105:
Step S101: detect user in the information of the selective call subscriber's extension station of doorway Selection of chiller, set up doorway main frame and be connected with the communication of selective call subscriber's extension station.User at doorway main frame calling party extension set, for example, calls out the extension set of Room 301.After calling through, set up doorway main frame and be connected with the communication of 301 Room subscriber's extension stations.By doorway main frame just can engage in the dialogue with the subscriber's extension station of Room 301, the communication such as video.
Step S102: detect selective call subscriber's extension station and whether obtain the instruction that user allows to gather fingerprint, if so, allow doorway main frame to read user's fingerprint.After step S101, selective call subscriber's extension station has been set up communication with doorway main frame and has been connected.Now, need selective call subscriber's extension station to carry out after mandate, the button that is for example preset in selective call subscriber's extension station by some sends after authorized order, and doorway main frame just can be obtained the authorization and be gathered the operation of fingerprint.Can avoid like this problem of the crime of illegal collecting and supplying blood finger print information that some maloperations cause.Can solve that lawless person distorts that tradition gathers the doorway main frame of finger print information and the problem that obtains authentication, the security that effectively improves whole system simultaneously.This step comprises the situation that selective call subscriber's extension station is initiatively authorized, and also comprises that selective call subscriber's extension station gathers the situation of user fingerprints according to doorway host requests mandate.Both of these case all needs user's doorway main frame after selective call subscriber's extension station is confirmed could obtain the mandate that gathers fingerprint.The in the situation that of selective call subscriber's extension station with no authorized, from doorway main frame, be unilaterally to carry out fingerprint collecting.Be different from and existingly at doorway main frame, gather the pattern of fingerprint storage in the main frame of doorway.
Step S103: doorway main frame fetching finger mark is converted to biological attribute data, sends described biological attribute data to selective call subscriber's extension station.After step S102, the doorway main frame collection fingerprint of obtaining the authorization, and fingerprint is converted to the biological attribute data that treatment circuit can be stored and identify, this characteristic is sent to selective call subscriber's extension station.
Step S104: the subscriber's extension station calling through receives and store described fingerprint characteristic data as biological information counterfoil.Subscriber's extension station is stored this biological attribute data, the contrast comparable data using it as follow-up identification.
Step S105: doorway main frame shows event memory, and carry out continuous fingerprint characteristic data input or finish fingerprint input according to user command.Doorway main frame shows by LED or several display types of LCD, as LCD Chinese display, points out " continuing input fingerprint ", and LED shows that prompting users such as " NEXT " continues to input fingerprint.
Step S20: doorway main frame receives user's finger print data in real time, and send it to all subscriber's extension stations.This step is mainly the identification step in follow-up use procedure, is different from the identity storing step of step S10.Due in actual use, the quantity of doorway main frame is often limited, and the quantity of subscriber's extension station is more, is in most cases the situation of one-to-many.Want to contrast fingerprint, will all send the fingerprint collecting to all subscriber's extension stations.When the user who has authenticated inputs fingerprint in the fingerprint capturer of doorway main frame, main frame conversion in doorway is also sent to all subscriber's extension stations in broadcast transmission mode by the fingerprint collecting.Broadcast mode can reduce the stand-by period, accelerates the process of whole fingerprint recognition.
Step S30: whether the fingerprint that subscriber's extension station contrast receives is in real time consistent with fingerprint counterfoil, and feeds back comparing result to doorway main frame.All subscriber's extension stations receive the fingerprint that is converted to biological attribute data that doorway host broadcast sends simultaneously, the fingerprint of Real-time Collection and fingerprint counterfoil are compared simultaneously.If the match is successful, subscriber's extension station feedback comparing result is to doorway main frame; If compare failed subscriber's extension station, do not feed back comparing result.Such benefit is can solve many extension sets to send the communication data collision problem bringing, avoid too much data to cause the strict problem of demand such as hardware configuration, software optimization of doorway main frame, can greatly alleviate the burden of doorway main frame, speed up processing, makes system increase extension set and user but can not increase the processing time.
Step S40: doorway main frame display comparison result, in limiting time, do not receive comparison result, judge that this user is for nonregistered user.For erroneous judgement, doorway main frame, gather the consideration that fingerprint is inaccurate, input the problems such as fingerprint by mistake, doorway main frame is not received comparing result within a certain period of time, and not this fingerprint is described in all extension sets.Doorway main frame shows by LED or several display types of LCD, as LCD Chinese display, points out " fingerprint recognition is made mistakes ", and the prompting users such as LED demonstration " _ ERR " continue to input fingerprint, again contrast.Then within the time limiting, also there is not feedback result, can judge that this user, for nonregistered user, can not pass through.
Step S50: doorway main frame is controlled unlatching or the demonstration information at gate according to the comparing result of subscriber's extension station feedback.According to institute above, can learn in steps, if fed back comparing result, doorway main frame is opened gate, lets pass, otherwise does not open gate.The information showing comprises the informations such as refusal clearance.
